 |
|
Hi all,
I've updated my system today, and udisks:2 got pulled in. Now the mountpoint of external devices mounted through thunar appear in /run/media/{username}/{deviceID} (from /media/{deviceID}).
I also have my distfile directory on an external disk. In /etc/portage/make.conf DISTDIR was set to "/media/{deviceID}/gentoo/distfiles", after the upgrade to udisks:2 I modified that line to "/run/media/{username}/{deviceID}/gentoo/distfiles". So far so good.
Now, when I try to downgrade udev (for some other reason) I get the following:
| Code: | $ sudo emerge -avF udev
These are the packages that would be fetched, in order:
Calculating dependencies... done!
[ebuild UD ] sys-fs/udev-208 [212-r1] USE="acl firmware-loader gudev kmod openrc%* -doc -introspection (-selinux) -static-libs" ABI_X86="(64) (-32) (-x32)" 0 kB
Total: 1 package (1 downgrade), Size of downloads: 0 kB
Would you like to fetch the source files for these packages? [Yes/No]

Apparently, portage cannot write to the new location, but let's leave that aside for the moment. Now when I execute
| Code: | sudo emerge -av udev
These are the packages that would be merged, in order:

I noticed that the permissions on /run/media are somewhat special:
| Code: | ls -la /run/media
total 0
drwxr-xr-x 3 root root 60 May 20 17:41 .
drwxr-xr-x 21 root root 580 May 20 17:42 ..
drwxr-x---+ 3 root root 60 May 20 17:41 {userID}
|
Questions:
1. why can portage access the distfile directory and check the files when running emerge -F but not when trying to actually emerge the package?
2. if this is a permission problem on /run/media/{userID} how do I modify them?
Thanks! |
