Functions ¶
func FileSHA256 ¶ added in v0.13.0
FileSHA256 returns the SHA-256 digest of the file at path.
func InstallFile ¶
InstallFile streams source onto target atomically. Large executables are copied rather than buffered in memory.
func MountedNoexec ¶ added in v0.13.0
MountedNoexec reports whether the filesystem holding path is mounted without permission to run programs from it, so a binary placed there cannot run.
func SyncFilesystems ¶
SyncFilesystems persists every filesystem backing the given paths.
func SyncOpenFilesystems ¶
SyncOpenFilesystems synchronizes each distinct filesystem once, using open handles that stay valid after teardown removes their paths.
