prefixes parse to IEC values (1KB=1024B). Later, support for parsing IEC prefixes was added, also parsing to IEC values (1KiB=1024B). To maintain backwards compatibility for the long-used implementation, no fix is provided for SI prefixes (to make 1KB=1000B may now violate user expectations). Future prospective callers of this function should consider implementing a new function with more standard expectations (1KB=1000B and 1KiB=1024B) Examples: 10M => 10485760 10MB => 10485760 10MiB => 10485760 �iBN���r� r r� r� r� r� l )r� �K�M�Gr� r z'%s' is not valid input.z'%s': cannot be negative)r� rQ r� r� r, )r� �size_inr� �num�mplierr r� r1 r1 r2 � human2bytes s, � �� r� c C s< | du r t �� d } | dkp| d dko| dd� dk}|S )z$Return True if platform is x86-basedNr0 �x86_64r rw r) �86)r- r. )� uname_arch�x86_arch_matchr1 r1 r2 �is_x866 s �r c C s, t jd d� dk rt�t�| ��S t�| �S )Nr) )r) � )r � version_info�email�message_from_filer� �StringIO�message_from_string)r� r1 r1 r2 r @ s r c C s� t j ddg| dd�}t� }|j�� D ]+}z |�d d�\}}}W n ty( Y qw |�d�s3|�d�r=|�t� dd |�� q|S ) Nz dpkg-queryz--listT)r7 r6 r) �hi�iiz:.*r� ) r r2 r8 rN r0 r� ra r7 rC �sub)r7 r: � pkgs_instrX r� r� r r1 r1 r2 �get_installed_packagesF s ��r c C s� d} zt t| dd��}|�dd��� dkrW dS W n ty2 } z t�d| |� W Y d }~nd }~ww t� }d|v r<dS td dd�}d|�� v rJdS tj � d �rRdS d S ) NrK T�r� r@ r� z ubuntu-corez!Unexpected error loading '%s': %sz snap_core=z /etc/system-image/channel.iniz/etc/system-image/config.d/F) rT r� rU r� r� rR rS r r- r r� )�orpath�orinfor� r rJ r1 r1 r2 �system_is_snappyU s& ��� r c C s� d }| � � D ]}|�d�r|dd � } nq|d u r d S |�d�r#|S |�d�r2d|td�d � S |�d�rCd|td�d � �� S |�d�rhd |td�d � �� }tj�|�r\|S t|�}|rf|d S |S d| S ) Nzroot=r� rq r[ z/dev/disk/by-label/zUUID=z/dev/disk/by-uuid/z PARTUUID=z/dev/disk/by-partuuid/r )r0 ra rQ r� r- r r� r� )r r] r� � disks_path�resultsr1 r1 r2 �rootdev_from_cmdlinem s0 � � r c C sF dd� }i }|| �D ]}|� dd�\}}|s|}|s |r |||< q |S )z�Given shell like syntax (key=value key2=value2 ) in content return the data in dictionary form.
