All,
I want to convert the growroot functionality to a proper systemd service but I'm struggling. I (think I) want it to run and finish before the filesystems are checked and before /sysroot is mounted. For testing purposes, I replaced the growroot script with a simple script that sleeps for 5 seconds and emits debug messages at the beginning and at the end. What I end up with is that fsck is started before growroot and I can't seem to figure out why that is. What I have at the moment is:
[Unit]
Description=Grow the root partition
After=systemd-readahead-collect.service systemd-readahead-replay.service
Before=systemd-fsck@.service sysroot.mount
[Service]
Type=oneshot
ExecStart=/bin/growroot
StandardOutput=syslog+console
StandardError=syslog+console
RemainAfterExit=yes

Also, I suspect I need to add this service to a target unit. What would be the most appropriate one? Currently it's initrd.target.
Thanks
