I could change linux-base.postinst to avoid adding space between name,
'=' and value when updating the configuration but it seems simple enough
to make ybin accept that too.
Yes, it's simple. And I think you can't avoid the quotes, because of
spaces ? (I bet some people put spaces in FS labels ?). So yes, ybin
needs fixing, I'll try having a look at that (and Rick's code).
If you're going to have a look at the ybin patches, I've got a couple of
bugfixes (attached)

"Usage: $PRG [OPTION]...
Update/install bootloader onto a bootstrap partition.
-b, --boot set bootstrap partition device [ -b /dev/hda2 ]
-o, --ofboot set bootstrap partition OpenFirmware device
default: automatically determined [ -o hd:2 ]
--bootonce override default boot label for ONLY next boot
eg: --bootonce linux-2.6.20-testing
-i, --install pathname to the actual bootloader binary
default: /usr/{local/}lib/yaboot/yaboot same as
install= in config file [ -i bootloader_file ]
-C, --config use alternate configuration file (ybin and yaboot)
[ -C config_file ]
-m, --magicboot pathname to a OpenFirmware magicboot (CHRP) script
--filesystem set the filesystem type of the bootstrap partition
available options are hfs, msdos, and raw
[ --filesystem hfs ] default is hfs
--nobless don't bless the root directory, this should only
be used if you are using a MacOS boot partition
as the bootstrap partition (not recommended)
-M, --mount don't use userspace hfsutils to modify the
bootstrap instead try and mount the filesystem
directly. Note that attributes cannot be set
this way and you will have to manually modify
OpenFirmware to make your system bootable
--protect set the read-only (locked) bit on all bootstrap
files
--hide set the invisible bit on all bootstrap files
this is useful of you don't want them to be
visible from MacOS.
--nonvram do not update the boot-device variable in nvram.
--force don't ever ask for confirmation
-v, --verbose make $PRG more verbose
--debug print boring junk only useful for debugging
-h, --help display this help and exit
-V, --version output version information and exit"
