I am attempting to do the very simple task of moving file.gz from /home/username/Downloads/file.gz into /mnt/gentoo/proc/When I issue mv /home/username/Downloads/file.gz /mnt/gentoo/proc/ it returns with mv: cannot create regular file /mnt/gentoo/proc/file.gz: No such file or directoryls /mnt/gentoo/proc gives the huge list of files that are indeed in that directory. ls /home/username/Downloads/ gives just file.gztouch /mnt/gentoo/proc/file.gz didn't work and gave me touch: cannot touch /mnt/gentoo/proc/file.gz: No such file or directory I can indeed move file.gz to other directories, but not into the one I want it in.Output of mount is: /cow on / type overlay (rw)proc on /proc type proc (rw,noexec,nosuid,nodev)sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)udev on /dev type devtmpfs (rw,mode=0755)devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)/dev/sdd on /cdrom type iso9660 (ro,noatime)/dev/loop0 on /rofs type squashfs (ro,noatime)none on /sys/fs/cgroup type tmpfs (rw)none on /sys/fs/fuse/connections type fusectl (rw)none on /sys/kernel/debug type debugfs (rw)none on /sys/kernel/security type securityfs (rw)none on /sys/firmware/efi/efivars type efivarfs (rw)tmpfs on /tmp type tmpfs (rw,nosuid,nodev)none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)none on /run/shm type tmpfs (rw,nosuid,nodev)none on /run/user type tmpfs (rw,noexec,nosuid,nodev,size=104857600,mode=0755)none on /sys/fs/pstore type pstore (rw)binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd)gvfsd-fuse on /run/user/999/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=mint)/dev/mapper/vg2-root on /mnt/gentoo type ext4 (rw)/dev/mapper/vg1-home on /mnt/gentoo/home type ext4 (rw)none on /mnt/gentoo/proc type proc (rw)/sys on /mnt/gentoo/sys type none (rw,bind)/dev on /mnt/gentoo/dev type none (rw,bind)Output of df -hFilesystem            Size  Used Avail Use% Mounted on/cow                  3.9G  113M  3.8G   3% //dev                  3.9G   12K  3.9G   1% /mnt/gentoo/devtmpfs                 794M  1.8M  792M   1% /run/dev/sdd              1.5G  1.5G     0 100% /cdrom/dev/loop0            1.5G  1.5G     0 100% /rofsnone                  4.0K     0  4.0K   0% /sys/fs/cgrouptmpfs                 3.9G  660K  3.9G   1% /tmpnone                  5.0M     0  5.0M   0% /run/locknone                  3.9G  1.5M  3.9G   1% /run/shmnone                  100M   32K  100M   1% /run/user/dev/mapper/vg2-root  110G  4.7G  100G   5% /mnt/gentoo/dev/mapper/vg1-home  917G   72M  870G   1% /mnt/gentoo/home
