| mathiaz | Hi. In the minimal iso install, is it possible to put a preseed file on the minimal iso ? | 19:56 |
|---|---|---|
| cjwatson | mathiaz: yes, but it's fiddly; wouldn't it be easier to fetch it from the network? | 20:06 |
| cjwatson | BTW, "minimal iso" isn't a good description. Do you mean "netboot mini.iso"? | 20:06 |
| mathiaz | cjwatson: yes - I refered to netboot. | 20:07 |
| mathiaz | cjwatson: it's another option. I was just wondering if that could be possible. | 20:07 |
| cjwatson | you can do it and then use file=/cdrom/path/to/file, sure | 20:07 |
| mathiaz | cjwatson: I'm already using fuseiso to setup a preseed on the ubuntu-server cd for automatic installation. | 20:07 |
| cjwatson | just if you're netbooting it's normally less hassle just to put it on the network and use url= | 20:07 |
| cjwatson | (that's what I do) | 20:08 |
| mathiaz | cjwatson: I was wondering I could do the same with the netboot min.iso | 20:08 |
| cjwatson | oh, let me just double-check that file-preseed is available there | 20:08 |
| cjwatson | mathiaz: ah, no, sorry, you can't do it in the usual way. The netboot installation method doesn't actually mount the CD from Linux at any point | 20:09 |
| cjwatson | mathiaz: you can, however, unpack the initrd and add /preseed.cfg to it, then repack it | 20:10 |
| mathiaz | cjwatson: ok. Thanks. | 20:10 |
| cjwatson | '(cd /path/to/unpacked/initrd && find . | cpio --quiet -o -H newc) | gzip -9 > /path/to/new/initrd.gz' does the repacking | 20:11 |
| cjwatson | any file called /preseed.cfg in the initrd will automatically be read as a preseed file | 20:11 |
| mathiaz | cjwatson: It may be interesting to add cd mounting in the netboot mini.iso also. | 20:11 |
| cjwatson | not a good idea IMO, netboot is used by people who have trouble mounting CDs | 20:12 |
| cjwatson | (among others) | 20:12 |
| cjwatson | I don't want to complicate the netboot path for the very rare cases where mounting the CD is useful | 20:12 |
| mathiaz | cjwatson: good point. But they're able to boot from their cd drive | 20:12 |
| cjwatson | that's not the same as Linux being able to read from it, though | 20:13 |
| cjwatson | I have a lot of bugs that say that | 20:13 |
| mathiaz | cjwatson: ok. | 20:13 |
| mathiaz | cjwatson: so if you fetch the seed from the network, you need to specify on the command line every time ? | 20:13 |
| mathiaz | cjwatson: or do you modify the isolinux.cfg on the mini.iso so that it fetches from the preseed from the network ? | 20:14 |
| cjwatson | the former for testing, the latter in production | 20:15 |
| cjwatson | the only reasons anyone uses netboot mini.iso seriously anyway are (a) testing (b) Linux can't cope with their CD drive ;-) | 20:16 |
