#.      When writing programs I like to never use relative paths with AT_FDCWD
#.      because. Because making assumptions about the current working directory
#.      of the calling process is just too easy to get wrong; especially when
#.      pivot_root() or chroot() are in play.
#.      My absolut preference (joke intended) is to open a well-known starting
#.      point with an absolute path to get a dirfd and then scope all future
#.      operations beneath that dirfd. This already works with old-style
#.      openat() and _very_ cautious programming but openat2() and its
#.      resolve-flag space have made this **chef's kiss**.
#.      If I can't operate based on a well-known dirfd I use absolute paths
#.      with a -EBADF dirfd passed to *at() functions.

#.  Christian Brauner
#.      When writing programs I like to never use relative paths with AT_FDCWD
#.      because. Because making assumptions about the current working directory
#.      of the calling process is just too easy to get wrong; especially when
#.      pivot_root() or chroot() are in play.
#.      My absolut preference (joke intended) is to open a well-known starting
#.      point with an absolute path to get a dirfd and then scope all future
#.      operations beneath that dirfd. This already works with old-style
#.      openat() and _very_ cautious programming but openat2() and its
#.      resolve-flag space have made this **chef's kiss**.
#.      If I can't operate based on a well-known dirfd I use absolute paths
#.      with a -EBADF dirfd passed to *at() functions.
