Hey,

I have MacBook Pro that has only wifi for communication,
I have to add the Wifi's firmware into the lib/firmware folder that is required by the driver,

Problem is that booting from the minimal cd, the /mnt/livecd is mounted as read-only,

Is there any way to make the /lib/firmware folder write accessible ? or maybe there is another approach ?





Thanks,


Asaf.

Hi!

You can also search alternative bootable Linux that do have more firmware, such as SystemRescueCD (based on Gentoo).

You don't need a Gentoo CD to install Gentoo, you only need a running Linux.

yea I know,

I was more curious whether it's possible to attach an in memory storage (i.e tmpfs) into the
lib/firmware/X folder even though the base mount is based on the ISO


Thanks.

trouby,

You can put /lib/firmware on a memory stick and mount that at /lib/firmware.
The rootfs on the liveCD actually uses an overlay filesytem of some sort, so its not read only but changes are not persistent.

You will find that you need other things to get your wifi to work, firmware is only the start.
e.g. wpa_supplicant to get the wireless part of the link established.

The Gentoo LiveCD is not a good starting point if you need Wireless to install but you can do the base install using sneakernet, if you really want to do it the hard way, and not have networking until you are on your own kernel.

Gentoo LiveCD is working more predictable from cli, comparing to SRCD.
The same Access Point, same computer, same wi-fi adapter and the same command line steps. But at the:
Code:

# wpa_supplicant -D nl80211 -iwlp0s29u1u1 -c <(wpa_passphrase MYSSID passphrase)

SRCD doesn't connect because of 'wrong key', while GentooLive does.
From the other side, SRCD has X.org on board, and if I set wifi through GUI - connection is successful.
Why that? TTY issues?

Some command syntax is different when I used sysrescuecd on several instalations regarding the gentoo handbook. as a long term user since pentium 1 days, its kinda easy to fix that.

The minimal cd is rather useless and sysrescue is not that big

Personal opinion: Linux mint livecd gives you full browser and other stuff while beeing able to install gentoo. (lazy man approach)

ofc check if all those cds are amd64 when you need for example amd64...
