How often should I run emerge --sync?

Jojobinha_2009

I do run on "~amd64" so I do get updates every single day (not complaining)...
I've read that a Gentoo install shouldn't be left without updates for long periods of time since that can result in system breakage when the user does try to update his/her system.

But how many times a day or a week should I run updates?

Jojobinha_2009,

emerge --sync, not more than once a day or you may get your name it the naughty book :)
The mirror rotation blocks users that sync excessively. FOr some period of time.

I have about 10 installs here, so I run a private rsync mirror that updates daily in a cron job.
My installs sync with that.

Do updates at least once a month on an all testing install.

Jojobinha_2009,

Yes. If there are problems, try again.

I run sync daily to my local rsync mirror, while I sleep via crontab, which emails me the results, then emails me the output of "emerge -uDU @world -p" which I usually apply each morning to my two main machines. It takes almost no time (I don't watch it build.) and prevents many problems.

Twice a week...

Historical really: gentoo was a bit wilder back in the day, network & cpu was slower, and daily meant I was spending more time updating than using.

My contraption as follows:

a Raspberry Pi wakes up the main Gentoo PC at 3am twice a week.
the main Gentoo PC has a cron script set to run just after the expected wake-up times
the cron script syncs and then does an emerge --fetchonly to download the new sources
if there are no interactive users, the script shuts the PC down
the report gets emailed to me, so i can decide when to kick off the build.

The other PCs share the gentoo repo/distfiles via nfs.

Juippisi,

Is there a way to use git mithout putting all the bits together for yourself?

Also, rsync does resume but I don't think git does.

wjb,

That sounds a bit Heath Robinson. The Pi can do all that, why wake the PC?

@NeddySeagoon

'Fraid none of the Pi's run Gentoo at this point in time. Waking up the main PC to do something it already knows how to do seemed the simplest option.

Juippisi,

Thank you. I'll try that.

You try internet using wifi to the open wifi on passing buses. :)

figueroa,

Yes. git only works into a git repo, which /usr/portage isn't it it was populated by rsync.

You can move the existing /usr/portage out of the way to start with and delete it later.
