The _mntopts does not means the real "mount options" it's just a string
for
cancat and create a fstab line then pass to dracut. Currently it contains
the mount target and mount options, and it contains fs_freq and fs_passno
after this patch.
That's an implementation detail. dracut does not promise that it is going
to put this in a /etc/fstab file. What if dracut directly decides to
use mount command.
mount -t <filesystem ype> -o <filesystem options> <device>
<mountpoint>
In this case mount will fail if you decide to pass 0 and 2. For example
I tried following and it failed.
mount -t ext4 -o data=ordered,0,2 /dev/sdb /mnt/wd-ssd1/
While following succeeded.
mount -t ext4 -o data=ordered /dev/sdb /mnt/wd-ssd1/
That's why I am insisting that we modify dracut man page and make it
explicit. fs_freq and fs_passno are not mount options. You try to pass
them as mount options, and mount will fail.
Probably should we change the local variable name to something "_line"?
Or explicity use local variable names as fs_freq and fs_passno (taken
from fstab man page).
