thanks for the hint !
Anyway it does not seem easy to install altboot in cacko:
1- wc, tr are in /usr instead of /bin, but /usr is not mounted :-(
2- altboot cannot find /etc/altboot-*.conf because /etc seems to be overwritten
For 1, I can copy the missing binaries, but how much space left is there
on / ?
And for 2, how can I access the original /etc, before it gets replaced
by a link to /home/etc ??
