you can also add the fact that the menu.lst symlink can be removed, since it can only make matters worse. |

erm |
| 27 |
/lib/modules/2.4.22-hardened is not a directory. |
| 28 |
No dep file found for kernel 2.4.22-hardened |
| 29 |
and so on ... |
| 30 |
|
| 31 |
I've only made an ugly hack to make it create my initrd.gz, if you are interested I think I could do a cleaner diff on this issue. |

there are interesting ideas on the selinux list, and as I see it a lot of people is against initrd |
| 46 |
for compatibility reasons (the Sun/Cobalt Qube/RaQ hardware which has a Linux kernel in the BIOS which can read an Ext2/Ext3 file system and load a kernel - they never wrote code for loading an initrd) to quote Russel) |
| 47 |
|
| 48 |
maybe a good solution will pop up in the near future. |
