I recently had to reinstall Windows 10 on my dual-boot GPT+UEFI system that primarily uses Manjaro.
I ended up restoring Manjaro from backup in such a [mistaken] way that there are now two versions of each package in /var/cache/pacman/pkg.
Q1: Is it safe to delete /var/cache/pacman/pkg/* ?
With all the EFI’s (rEFInd, Windows 10, Linux, at times even FreeBSD) in my ESP, my ESP usage never goes beyond 30 MB in
df -h. I was earlier following the Linux recommendation of 512 MB ESP (vfat). In the recent reinstall+restore, I just used a 128 MB ESP (msdos/fat16). And the system works damn well.
Q2: Why does Linux recommend 512 MB vfat ESP when 64 MB (max 128 MB) is a more reasonable value ? And why vfat when fat16/msdos works equally well ?
Thanks for any inputs,
