I just depcleaned 164 packages...HELP [CLOSED]

I know that many of the packages that were probably just removed after running a complete update on this system are either programs I just installed for a one time need or something sort of like that. I wonder why I just let the 5 seconds go by instead of killing the countdown before it unmerged since I saw it was going to be a lot of packages. To be honest I am not sure what half of these packages have to do with. I am aware that there would be a way to looking up the answer if I was prepared to type it into google 163 times or whatever.

This is really frustrating because it is the second time this week I thought I lost the Firefox browser (which I know takes about 4 hours to compile on my machine, which is fairly inconvenient given that it is a laptop which makes it likely to be interrupted often with startinng and stopping and leaving or taking it with me etc.). This time the browser is actually gone! Which is weird I guess because I actually have it open at the moment to write this post!

In the end, this will just be another reason to start using the binary package store on my desktop machine for this situations and others like it.

The entire last day I spent compiling code, so it doesn't make sense unless I want to repeat all that work to restore a previous backup. Assuming that I am stuck having to "recompile" this list of packages, where and how would I start. Do I just pass them all along in the command shell? Or would it make sense to add them to a file first and then tell Portage to merge all the packages in that set...Which packages in this list are the dev-*/* or x11-*/* packages and are they generally necessary/unnecessary? Here's the list of packages...that were unmerged. https://paste.pound-python.org/show/t3ZextLTa4ZXO9ULLm1S/

Basically what I am looking for is someone to take a quick look down this list for things that I should probably reinstall....
Considering that I am trying to make for a good general purpose user + developer type of platform environment, which languages, and libraries etc. need to be included again.
Alternatively, if it makes sense perhaps what I would do is reinstall everything, or else restore from a recent backup and run --noreplace before doing the --depclean in the future. Any suggestions for what to do next?

LIsLinuxIsSogood ...

when I look at that 'qlop -u' output I'm inclined to thing you're reading it wrong, yes, there were packages unmerged, but you're not seeing 'qlop -l', those packages that were not removed, per se, but updated, eg:

LIsLinuxIsSogood,

Regarding firefox being missing, have you been emerging new things that you want to keep with the -1 or --oneshot option?

LIsLinuxIsSogood - maybe you should set

Good catch Neddy about the timestamps, yes other udates were running, but just one depclean at around the time of whenever the last packages in the list (so I guess around 12:55pm today PST). I didn't know that the unmerge history would also show the results of the previous updates, so that does answer some of the concerns. The buildpkg USE flag is definitely something I will consider, but I am working on a system that is very strapped for space (total 240GB, which after you account for a second operating system, and a couple of partitions for Wine and other software like that it doesn't leave a ton of room to mess with). Would the buildpkg result be able to be moved onto an external HD afterwards via some simple cp or rsync?

Thanks all for the input about the situation, but unfortunately the 164 packages I actually watched them get removed, which means I could have stopped it any time

you use --exclude for that.

Good point...closed due to user error

FEATURES=buildpkg writes to $PKGDIR, so if you have external storage you would prefer to use, you can point Portage to it by setting PKGDIR in make.conf. Take care that the storage is available during any build with FEATURES=buildpkg though.

So I've gone ahead and implented the PKGDIR on an external NFS share...would the reason for a sshfs share work better perhaps be due to the following errors:

The use case for sshfs and NFS is different. NFS does not provide transport layer security. If that does not matter to you, I would recommend NFS as it is older and designed for multi-user access.

That error looks like you enabled root squashing.

Krinn, agreed I will look at the thread definitely but this brings up another point itself about access to these alternative ideas to whatever ideas might be present on the wiki in general. So far the update is I just enabled buildpkg in order to make the future cases easier, and I've reinstalled just about a dozen or more packages (so not all of them yet...and I'm still waiting to maybe see about using the list as a emerge --oneshot again for now in case recovering my old system is of interest). So far I have not used the -1 option to reinstall firefox, which included about 10 other dependent packages that were removed as a result of my running depclean after removing it from the world set.
