This is my first time I was forced to "hand use" dracut, because
initramfs build by kernel install does not work (due to kexec-tool bug).
But I was surprised by few thinks:
1. dracut accepts as a kernel version non existing kernel name and
builds the initramfs - this is really crazy (there are some warnings,
but it tooks a bit of time before first "File does not exist".)
You are right.. will add a precheck.
Thanks.
2. dracut initramfs build takes ages compared to mkinitrd
Does it really matter? How often do you build an initramfs per week?
Well... speed allways mathers. I am not using it daily today, but
remember the time when I was looking for proper module preload
configuration for some rare scsi device and was building it very often.
I am under impression that with every kernel build you need to
regenerate initramfs, to have correct modules loaded on next reboot..
and this I was used to do very often. Then every delay counts.
edit /etc/dracut.conf and enable the hostonly option, then you will have a fast
initramfs build, as well as smaller images.
3. dracut spits some confusing warnings, I am not sure what to do with:
W: Possible missing firmware aic94xx-seq.fw for module aic94xx.ko
W: Possible missing firmware ql8100_fw.bin for module qla2xxx.ko
W: Possible missing firmware ql2500_fw.bin for module qla2xxx.ko
W: Possible missing firmware ql2400_fw.bin for module qla2xxx.ko
W: Possible missing firmware ql2322_fw.bin for module qla2xxx.ko
W: Possible missing firmware ql2300_fw.bin for module qla2xxx.ko
W: Possible missing firmware ql2200_fw.bin for module qla2xxx.ko
W: Possible missing firmware ql2100_fw.bin for module qla2xxx.ko
Am I doin' something wrong or this is expected behaviour?
Well, there are some modules which might require a firmware. Dracut is
only reporting that they are missing. Just in case...
Maybe I should suppress these warnings.. what do you think?
I would suppress them, let them print in "debug" mode.
