Yes, and all that can be accomplished without emaint!!!
emerge-webrsync and emerge –sync have been a part of Gentoo, for as long as I can remember!! emaint is just another, third party install, that one has to learn. A user must learn Gentoo first, and then decide on what other programs, that may or may not enhance their Gentoo experience!!!
Let me rephrase this!!! If you are doing a hard install for Gentoo use “-march=ivybridge” which is for this machine!!! If you are using VirtualBox for a VM then use “-march=mative” or just leave it alone!!!
Congratulations. From here on it gets easier.
Get some practice with portage… eg you might have some special app that you want to compile with non-default flags. I do that with R.
Portage is a very capable package manager… a bit like Freebsd ports.
I think it depends what qemu is emulating. If it is native x86_64 I guess you could use the march value for the host? I will see if I can find what virt-manager suggests.
That is the thing with Gentoo and the make.conf!!! If you do not set this, and other settings, before you update your profile, then Gentoo will use a default setting, to who knows what!!
Look at my screenshot, that make.conf is edited right after the stage3 emerge!!!
It is possible to run Gentoo with the make.conf, as is, but it would be very erratic!!!
I did my install with ethernet, then switched the internet link to wireless so I could use the ethernet port for printers.
I did not use NM. From memory I configured the local printer network as static with dhcpcd, but not sure how I did the wireless link… I will check… I remember doing wpa_supplicant by hand.
I looked. I used
net-wireless/iw
net-wireless/wireless tools
net-wireless/wpa-supplicant
