Robert, that file shouldn't be there, since our epel is actually a rebuild. I'll remove it

Ok, I see this epel-release in the epel1 repo that I installed via the wiki.

So I decide to install it, and it created an epel.repo.rpmnew file. I swicth around the files and try a 'yum update' and get:

epel/armhfp/metalink                                     |  47 kB     00:00 Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=armhfp error was No repomd file

One of the configured repositories failed (Unknown),  and yum doesn't have enough cached data to continue. At this point the only  safe thing yum can do is fail. There are a few ways to work "fix" this:

....

File /var/cache/yum/armhfp/7/epel/metalink.xml does not exist

So I put everything back.

I found this old email about epel, it said that the epel repos were 'broken' ?

when I tried to install it with 'yum install epel-release'  it says it's not available.

Is there a different way to install it?

For c7 we have this https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp, but for c8, there's nothing yet

Hello,

ownership/permissions on gpio device are like tis:

crw-------.  1 root root    254,   0 Jan  1  1970 gpiochip0 crw-------.  1 root root    254,   1 Jan  1  1970 gpiochip1 crw-------.  1 root root    254,   2 Jan  1  1970 gpiochip2 crw-------.  1 root root    246,   0 Jan  1  1970 gpiomem

while other device like ttys, are owned by root and "group owned" by tty, similar for video, disk, dialout etc.

wouldn't it be 'better' to  have these gpio devices  owned by root, "group owned" by a group other then root (gpio)?

(or did 'we' inherit that from further up/down the development chain?)

Yeap, that's inherited, I'm guessing you could write some udev rule to set the permissions you need (or even setfacl)

I didn't even go that route,  I just created a group, called gpio, added myself and the uid stuff is running under to it, changed the group permission on the devices to rw .  That way a user that is in the gpio group can use the devices,  it's easy and similar to how serial devices etc (by being a member of dialout) work

Would be convenient if the gpio devices in /dev could be treated the same, permission wise, as modem/ACM0-n  etc.
