Hi,
This morning I've been talking to Harald Hoyer about what sort
of commandline options dracut will be needing to find the /
filesystem beside root=UUID=1234567890 .
In most cases (normal disks, dmraid, mdraid, lvm, dmcrypt)
root=UUID=1234567890 should suffice.
However in certain cases for example dracut will need additional
info to find the disks.
We've come to the following plan for iscsi targets:
1) Extend the dhcp_root dhcp variable iscsi syntax to
be able include a username password, so:
iscsi:192.168.50.2::::iqn.2009-06.dracut:target66
Can become:
iscsi:user:pass 192 168 50 2::::iqn.2009-06.dracut:target66
Or:
iscsi:user:pass:reverse_user:reverse_pass 192 168 50 2::::iqn.2009-06.dracut:target66
2) Pass root-path=iscsi:... on the kernel cmdline, for each needed iscsi
target, so if
necessary this will be passed multiple times, dracut will be modified
to be able
handle multiple root-path arguments being passed in
3) chmod /proc/cmdline 400, so that it cannot be read by ordinary users,
plugging
the passwork leak problem
