I built LFS-7.7 on a PowerMac G4.
My host system was originally Ubuntu-server 8.04.1 (Hardy).
It got 2 major upgrades, first to Ubuntu 10.04.4 LTS (lucid) and then to Ubuntu
12.04.5 LTS (precise).
My machine has 3 ATA disks:
lfs@ppc125:~$ sudo lsscsi
[0:0:0:0] disk ATA IBM-IC35L090AVV2 V2HK /dev/sda
[0:0:1:0] disk ATA Maxtor 6Y160P0 YAR4 /dev/sdb
[1:0:0:0] disk ATA WDC WD5000AAKB-0 12.0 /dev/sdc
[2:0:0:0] cd/dvd HL-DT-ST RW/DVD GCC-4480B 1.03 /dev/sr0
[2:0:1:0] cd/dvd PIONEER DVD-RW DVR-110D 1.37 /dev/sr1
The first 2 Ubuntu releases reported the disks as /dev/hdx, but the third one
suddenly used /dev/sdx.
It took me some time to make my machine again bootable after the third upgrade.
Now I am finishing LFS-7.7-systemd on this machine and guess what: LFS again
turns to /dev/hdx…
I now have a quite strange (but working) yaboot.conf, with a mix of sdx (for
Ubuntu) and hdx (for LFS):
lfs@ppc125:~$ cat /etc/yaboot.conf
## yaboot.conf generated by the Ubuntu installer
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
## see also: /usr/share/doc/yaboot/examples for example configurations.
##
## For a dual-boot menu, add one or more of:
## bsd=/dev/hdaX, macos=/dev/hdaY, macosx=/dev/hdaZ
boot=/dev/sda2
device=/pci@f4000000/ata-6@d/disk@0:
partition=3
root=/dev/sda3
timeout=50
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
macosx=/dev/sdc10
image=/boot/vmlinux
label=Linux
read-only
initrd=/boot/initrd.img
append="quiet splash"
image=/boot/vmlinux.old
label=old
read-only
initrd=/boot/initrd.img.old
append="quiet splash"
image=/boot/vmlinux-3.19-lfs-7.7-systemd
label=LFS
device=/pci@f4000000/ata-6@d/@1
partition=2
root=/dev/hdb2
read-only
initrd=/boot/initrd.img-3.19.0
append=""
Does anyone have an explanation for this? Possibly a way to come to a more
consistent configuration?
BTW: I know that the LFS community doesn’t like initrd, but it looks to be the
only way to boot LFS on an iMac or a PowerMac.
Without it, LFS always hangs after “returning from prom_init…”
Or is there a way to avoid initrd?
