I have a, let's say LAN, of SPARC PC. What i want to do, is to install Gentoo on all of them.
Only one of them has a cd-rom device. At that machine i have already installed gentoo and now i
want to install it to the rest by somehow making the other sparc machines boot from my cdrom or by
creating a virtual installation place.

Does anyone know anything?I don't even known if something like this is possible so don't laugh!
Thanks in advance

Easy, if all the PCs are identical.

Just install normally on one PC, then make a stage 4 of the installation, and then "restore" the stage 4 "backup" on all the other PCs.

You can transfer the stage 4 any way you want - even move the hard drive around if necessary.

The other pcs move different hard drives as far as capacity is concerned and other differences which don't allow me to use your solution, if i have understand correctly.
Due to my interest, what happens if the pcs are identical but the one has Gentoo and the others are solaris? The same procedure can be done?

You could still do the same thing, but adjusting the installed stage 4 on the other PCs would be necessary. Maybe kernel recompiles would be needed to add / drop hardware support. I wouldn't try it. :oops:

Also, if you're planning to compile for PCs with different processors, make sure the stage 4 uses the CFLAGS suitable for the oldest PC, otherwise you will not be able to install the stage 4 on it.

Yes.

You'll have to adjust the bootloader setup if you want to retain solaris on those PCs that have it (ie, dual-boot solaris and gentoo).

Well what sparc boxes do you have ?

If they are SCSI based machines (like SS20 etc) then a nice cheap external SCSI cdrom will do, you can use it on all the machines in turn..

If its an ultra 5 / 10 or other IDE based SUn box then you could just swap a single IDE cdrom between them. OK I know its not the pretty option but it will get the job done.

If your machines are identical, you can image one machine and populate the others using udpcast
and a net boot.

See this site with a modified tftpboot resource:

The machine running the udpcast image server need not be a Sun, but the master image
of course would be based on the Sun (probably the one you set up by CDROM).

Forget the cdrom. Netboot them.
