    Oh. Really.

  11. acct-user/acct-group seems wrong

    My considerations about "problem" with constant uid/gid between machines.
    Hope i understood correctly motivations from glep 81.
    If we need a constant uid/gid for some packages, then we need something like /etc/services for uid and gid.
    For example, /var/git/meta-repo/user-uid.map and /var/git/meta-repo/group-gid.map.
    Format of these files could be:
    user-uid.map:
    UNAME  SP UID

    group-gid.map:
    GNAME SP GID

    Where:
      UNAME - user name
      GNAME - group name
      UID - user id
      GID - group id
      SP - spaces and/or tabs ([ \t]+)

    Then we should modify user.eclass a little. In such a way that enewuser and enewgroup must do 2 things:
    - consult these files for constant uid/gid(if, for example, -S is specified)
    - place package name which call enewgroup/enewuser in /var/lib/portage/group-pkg.map and /var/lib/portage/user-pkg.map respectively

    Example changes for enewgroup: 

    --- user.eclass.orig    2020-05-06 09:27:19.264986735 +0000

    After that we have info in /var/lib/portage/user-pkg.map and /var/lib/portage/group-pkg.map about what user/group is used by what packages. And can show this with equery module. If we see user/group without packages - this entry is orphaned. We can show this with a same equery module and give a user possibility to remove this with some ego module(something like "ego user cleanup" and "ego group cleanup").

    Lego12239,

    I am not sure what you said is true. After all, Gentoo provide openrc from the very beginning when there is no systemd.

    You can't avoid systemd simply by installing openrc. Many binaries of systemd package can still be in a system. In funtoo you can easily do: 

    epro mix-ins no-systemd

    In gentoo(when i tried it) this can't be done so easy.

    But this complex is for both funtoo and gentoo

    I didn't say that in gentoo net conf is complex, i said that funtoo do it better ;-).

  21. exim MAIL FROM for external redirects

    in General Discussion

    Posted

    Hi, all.

    May be anybody know an answer and i can save some time :-). If i do an external redirect in exim, what MAIL FROM is used exim in smtp connection to an external server?

    example /etc/aliases: 

    me: me@gmail.com

    example email:
      

    MAIL FROM <somebody@his.server>

RCPT TO <me@my.server>

    my.server redirect it to gmail according to aliases:
      

    MAIL FROM <?????>

RCPT TO <me@gmail.com>

     

  22. grub2 doesn't see mdraid by mduuid

    in General Discussion

    Posted

    Hi, all!

    My grub doesn't see mdraid (raid1) by mduuid. /boot/grub/grub.cfg: 

    set timeout=2

menuentry 'Funtoo, 4.14.97' {
        insmod gzio
        insmod mdraid1x
        insmod part_msdos
        insmod ext2
        set root='(mduuid/232d2317:1469bc36:e85fd34c:9136eb63,msdos1)'
        echo    'Loading kernel...'
        linux   /boot/vmlinuz-4.14.97-nat root=LABEL=rootfs ro domdadm
        echo    'Loading initial ramdisk...'
        initrd  /boot/initramfs-genkernel-x86_64-4.14.97-nat
}

    If i replace "set root='(mduuid/232d2317:1469bc36:e85fd34c:9136eb63,msdos1)'" with "set root='(md/0,msdos1)'", then grub boot the system.

    Grub was installed with the next command(sda and sdb are raid component devices):
      

    grub-install --boot-directory=/boot/ --modules='part_msdos mdraid1x' /dev/sda

grub-install --boot-directory=/boot/ --modules='part_msdos mdraid1x' /dev/sdb

     mdraid UUID: 

    mdadm --detail /dev/md127 | grep UUID
              UUID : 232d2317:1469bc36:e85fd34c:9136eb63

     

    How can i fix this?
