Morning all and Happy New Year.
Has anyone managed to get X working in securelevel 1?
I get errors when it tries to open /dev/io, which isn't that surprising
(from man init):
" 1 Secure mode - the system immutable and system append-only flags may
not be turned off; disks for mounted filesystems, /dev/mem, and
/dev/kmem may not be opened for writing; kernel modules (see
kld(4)) may not be loaded or unloaded."
But I was talking to an OpenBSD user over the weekend who said that 2.7 somehow
manages to reserve access to certsain devices by running some kind of wrapper before
the securelevel is used (although that may be bull).
Has anybody managed this, or have any references for the OpenBSD way of doing it?
Thanks.
