Subject: [PATCH] udev repeat
|
|
|
|
systemd-udev exec IMPORT{program} in rules to get stdout of
|
|
program for storing some ENV vars. However due to some reasons,
|
|
the stdout of program cannot be gotten by systemd-udevd, which
|
|
cause some errors due to missing of ENV vars.
|
|
|
|
lv maybe lost after reboot, now we repeat to exec programs to
|
|
avoid lv missing.
