|Alpine Linux documentation [1] explains using busybox 'nameif' to rename
|ethernet devices.
|
|But it appears 'mdev' doesn't invoke the command:
|
| $ mdev -s -v 2>&1 | grep nameif
| [nothing]
|
|/etc/mdev.conf looks like:
|
| -SUBSYSTEM=net;DEVPATH=.*/net/.*;.* root:root 0600 @/sbin/nameif -s
|
|Note the change to 0600 octal, just in case. We also tried increasingly
|less-specific matches, without success:
|
| SUBSYTEM=net;.*
| net/.*
| net/(.*)
|
|Using ".*" does actually work. So it proves it is capable (using correct
|config etc.) but of course invokes the command excessively:
|
| # mdev -s -v 2>&1 | grep nameif
| mdev: running: /sbin/nameif -s
| mdev: running: /sbin/nameif -s
| mdev: running: /sbin/nameif -s
| [...]
|
|Is this a busybox bug, or have I been misled by the Alpine docs? What is
|the correct match?
|
|I found only very little information on mdev.conf, just the brief message
|in the "--help" message, please let me know if there is more somewhere.
busybox:
git show master:docs/mdev.txt
git show master:examples/mdev.conf
I personally have my own little shitty scripted EFI-stub based
boot system, and that does
xbase_mounts() { # {{{ $1=$BB [uses $MDEV_RUN; calls stty -isig]
echo '. Checking /{dev,sys,proc,run}'
xhavemnt $1 dev || $1 mount -n -t devtmpfs -o
mode=0755,exec,nosuid,noatime none dev
xhavemnt $1 sys || $1 mount -n -t sysfs none sys
xhavemnt $1 proc || $1 mount -n -t proc none proc
xhavemnt $1 run || $1 mount -n -t tmpfs -o
mode=0755,noexec,nosuid,nodev none run
#[ -e /sys/firmware/efi ] &&
#mount -t efivarfs efivarfs /sys/firmware/efi/efivars -o
nosuid,nodev,noexec
$1 stty -isig
if [ -n "$MDEV_RUN" ]; then
echo '. About to run mdev -s, waiting for some more
settlement'
$1 sleep 8
$1 mdev -s $MDEV_RUN
fi
}
But effectively i do not use it here; and never used it for
network stuff. (I only use it to populate a /dev/disk/by-uuid.)
It is all trial and error anyway i'd guess.
