I've done that successfully on two single-user workstations, but it failed when it came to try on the one multi-user production box that I maintain. I've posted to the lists about this a couple of times and received zero responses, so my guess is that my condition was sufficiently obscure that no-one else has experienced the problem[*]. A shame. I'll have to do a re-format and start from scratch upgrade, some time that I can get the system quiet enough for long enough. > Do make sure to boot a 6.x kernel with your 5.x userland and test things > out a bit - make sure your hardware probes, is reliable, etc. Ditto. This was how I discovered that the ataraid in the 6.x kernel does something sufficiently different to the one in the 5.x kernel that I couldn't get past the fsck of the /usr partition... Luckily enough of / was mounting successfully for me to back out to the (working) 5.x kernel. So: my two cents: it can work, but it's possible for it not to work, and care is required. [*] The production server is using a software RAID mirror on a pair of SATA drives on a low-end Intel P4/ICH6 motherboard, using ar(4), configured by atacontrol. Fsck on 6.x can't find any superblocks on /usr, but 5.5 is fine.
