[gentoo-user] A question regarding building Gentoo and UEFI vs Non UEFI

[Andrew Lowe <agl@wht.com.au>]

Dear all,
	In the past I had a non UEFI motherboard setup for my Gentoo machine.
The motherboard started failing so I took the opportunity to replace the
motherboard & CPU and also to buy a new SSD thingy to become the home of
my Gentoo install.

	I'm currently running, on a day to day  basis, the older hard disk, on
the new motherboard, but want to speed up the process of getting the new
SSD set up so I can swap over. Rather than booting into the SSD,
starting an emerge, and walking away, in other words, making my machine
useless for any number of hours, am I correct that there is no problem,
vis a vis, old hard disk built on non UEFI machine Vs new SSD built on
UEFI machine, of chrooting[1] from the old environment into new
environment and doing the building whilst I"m doing something productive
within the old environment?

	I just have this little niggling doubt, probably baseless, in the back
of my mind that there maybe something that may cause a problem for the
newly built stuff due to it not being natively booted in UEFI or
something like that when it was built.

	Anyone built their new machines like this who can allay my, probably
baseless, fears?

	Thanks,
		Andrew
