Hey everyone ,
i just posted like 2 days ago about my new gentoo installation and i already messed it up (not really that bad but p interesting) i was messing with a bunch of stuff and somehow messed up my UEFI stuff so when rebooting i noticed it doesn't boot and i can't even see gentoo in my laptop's uefi stuff and tried booting into "INTERNAL HDD" but failed
i didn't have a gentoo livecd on me but i had a Lubuntu one so
i booted using it did the chrooting routine had to attempt fixes couple times
and in the end fixing it by just regenerating the kernel and installing it and reconfiguring grub
pretty simple but was quite happy tbh when it booted
so i guess "moral of the story" : "don't mess up your uefi shit i guess " |

- Unbootable machine... been there, done that.
- Broken glibc... been there, done that.
- Broken gcc... been there, done that.
- Borked portage... yup.
- Accidentally wiping my system...
The possibilities are endless! |

I've done all the above! ... in a VM while testing, and I had backup images I liked that time I tried out prelink and it made everything segfault
Well okay, I did break things on production systems before too But nothing major while using gentoo yet, just minor things. I remember that time I did linuxfromscratch in 2001...
Edit: my most recent woe that made me troubleshoot for hours was simplefb (set with "see efifb as simplefb" since the kernel kinda recommends that), it worked great.. but I wanted to do a single GPU passthrough and I seen people turn off efifb first.. well okay, I'll do the same and turn off simplefb. Okay it turns off fine, no display. Start QEMU... promptly fills my syslog with 1GB of "write errors". At that point I didn't suspect simplefb at all and thought it was other things (and caused new problems that sent me in more wrong directions), turns out simplefb never truly released the card. Works great if I use efifb and turn it off.... |
